Status indicator light for moodlebox on raspberry pi 3b+

I installed a power button for my moodlebox on a raspberry pi 3b+ by following instructions listed here.

I would also like to install a status indicator light so teachers can see when moodle is running or not, so they don't try to power it on when it is already on, or off when it is already off. I tried using the txd pin on the pi as discussed here. The status indicator LED turns on for a few seconds while the pi turns on, and then the light turns off.

Any suggestions on how to get a status light working?

I have no idea...

I've seen next to no discussion about moodlebox in these forums so, unfortunately, you may well be asking this in the wrong place.

Hi Cade,

When you made your LED, did you also add code to control it so that it lights the way you want it to?

Have you seen the Pimoroni Blinkt! for the Raspberry Pi? Gives you seven LED's and there are a number of code examples for making it produce various displays.

I didn't add any code, I was under the impression the using the TDX pin would work without code.

Nope, sorry. In the link you mention, in the second entry, needing a script is mentioned. TXD is short for transmit data. In other words, you can control the blink of an LED connected to it by "transmitting" data.

MoodleBox originating from the West part of Switzerland is somewhat French biased. You might have ping the developer https://moodle.org/user/profile.php?id=6406.

You mean a LED of your own connected to the GPIO, right? The power LED soldered to the board should behave as expected.
